简介
Vehicular Ad Hoc Network (VANET) is an emerging paradigm and an upcoming reality in road transportation which is designed and developed to minimize the road accidents and fuel consumption by giving a prior alert on traffic condition and collision detection using Vehicle to Vehicle (V2V) and Vehicle to Roadside Unit (V2R) communication. VANET is said to be a subset of Mobile Ad Hoc Network (MANET) due to similar node characteristics such as self-configuring node and multihop routing for examples. Based on their similar characteristics, MANET routing protocols are used in VANET. However, at various perspectives, VANET and MANET differentiate each other such as power, speed and mobility. Hence, applicability of MANET topology based routing protocols should be re-evaluated thoroughly using IEEE 802.11p standard which is specifically designed and developed to be used with VANET communication. In addition, realistic mobility should be generated by considering urban and non-urban vehicular traffic. However, position-based routing protocols are more suitable than the topology based routing protocols as position-based routing protocols do not maintain topology of the network rather they use the vehicle position on the Earth’s surface. The vehicle positions are obtained from the satellite navigation devices such as Global Positioning System (GPS), Galileo, Compass and Glonass. The position-based routing protocols use vehicle position as a location id during routing. Generally, satellite obtained locations are prone to have error due to environmental effect and urban infrastructure. Due to this error, the real vehicle position …
